This is a sampling of some of them. This Workbench book provides detailed step-by-step photos and information for rebuilding the differentials with the best equipment, installing the gear sets, and converting to Posi-Traction for a variety of applications. Factory 31 spline axles came with the last two bearing configurations, but not with the first. It was later used for pick-ups and Broncos. Probably going to need to modify the inner apron a bit but thats fine.
The numbers can also tell you what car the rearend came in, though you need to look up the info online or in a Ford manual, as there are thousands of codes. It also explains how to select the right differential hardware, bearings, seals, and other parts, as well as how to set ring and pinion backlash so that the rear end operates at peak efficiency. This chart references the connection between the month codes and the actual month. In addition, this book provides a comprehensive identification chart to ensure readers properly identify the model and specifics of the 9-inch differential. I haven't got a clue.
Count the number of bolts on the rear end housing inspection cover. Can anyone tell what this is by the tag? Since these housings were a series of stamped-steel pieces all welded together, there were many different overall lengths, tubes sections, mounting brackets, and even general constructions over the years see Chapter 5. Both standard and W-series cases are made out of gray cast iron. Unfortunately, the same codes were reused in different years. There are quite a few companies making Ford 9-inch housings to fi t just about any muscle car out there, including non- Ford vehicles. There is a huge aftermarket support for this axle design.
Mine is an independant from a 95 t bird. Verify both the axle tag and door-tag codes to determine whether the vehicle still has its original rear end. Some of this information is very important as it is becoming more and more difficult to find documentation on axles and differentials that were built more than 40 years ago. I wanted to let everyone know that this is a great option to a gm 12 bolt and is its equivalent but more affordable option. And looking at the axle tag above, you can see it's a 3. It was removed out of a 1989 lincoln mark 7 with an 5. Hypoid offset is the distance between the centerline of the pinion and the centerline of the ring gear.
The N cases typically came with the larger Daytona-style pinion support bearing, and 31-spline axle shafts. Some even consider these axles to be bulletproof. Ford vehicles use a number of different differential units, consisting of Ford manufactured differentials or those manufactured by the Dana Corporation. In order to verify a nodular unit, you need to look on the inside of the casting. This format is also applicable to casting date codes.
The Ford Mustang and Thunderbird used this style for a few model years. These axles had a stout 2. There are three versions with external Ns cast in; note the more curved style on the top right. The 1330 is usually found in Ford trucks. Here are a few things to help you differentiate between a 7.
There are four versions of the nodular iron third members that were produced from the factory. Starting in 2011, both the V6 3. On this particular third member, the original copper washers that were under the factory fasteners have been discarded as well. It covers the following year model Mustangs: Ford Mustang - 1979 79 - 1980 80 - 1981 81 - 1982 82 - 1983 83 - 1984 84 - 1985 85 - 1986 86 - 1987 87 - 1988 88 - 1989 89 - 1990 90 - 1991 91 - 1992 92 - 1993 93 - 1994 94 - 1995 95 - 1996 96 - 1997 97 - 1998 98 - 1999 99 - 2000 00 - 2001 01 - 2002 02 - 2003 03 - 2004 04 - 2005 05 - 2006 06 - 2007 07 - 2008 08 - 2009 09 - 2010 10 - 2011 11 - 2012 12 - 2013 13 - 2014 14 5. These axles even have a unique bolt pattern of five on 5 inches. In 1963, Ford included more information.
It must be referenced to a Ford Axle model listing, which gives the year, original application and differential ring-gear size. The Daytona- style cartridge allows for a larger pinion head bearing when compared to the standard pinion cartridge. There were many instances of cuts and scratches from the thin steel tags sticking up on the axles. This bearing is one of the reasons that the 9-inch has the reputation for being bulletproof. Some tags reference the week of the month instead of the exact day and just use a letter A to E for first through the fifth week of the month. Ford rear ends, or differentials, were manufactured by either the Dana Corporation or Ford.
The bottom line begins with the ratio being the first set of numbers. This additional bearing and, more importantly, the necessary casting support structure is what drives the larger hypoid offset. . There are several reasons for this. All of the 8-inch case nuts can be accessed with a socket.
The tags were replaced with adhesive labels that are placed around the axle tube near the brake and wheel end. The model number is located on the top right hand corner of the tag, J210-S, for example. At this width, many were used in street rod applications without modifi cation. It also has a 9-inch ring gear. Written by Joe Palazzolo and Republished with Permission of CarTech Inc. There are 24 different Fords that offered the 8.
